I'm 200 pounds and I want to get lipo and lose 50 pounds. Is that possible with Lipo?

Always remember that liposuction is an aesthetic procedure and not a weight loss procedure. With that in mind I would follow a strict diet and exercise  program to lose the weight and then see a plastic surgeon for possible body contouring procedures. Best of luck.  

Unfortunately, liposuction does not result in much weight loss.  It is a contouring procedure to remove areas of excess fat.  It is not possible to lose the kind of weight you desire with liposuction.
